Basic requirements:

1.Citrix Provisioning Services 7.13 (software version no less than 7.13)

2.Citrix XenServer 7.1.0 (software version no less than 7.1.0)

3.PVS Accelerator is suitable for XenServer Enterprise Edition customers or authorized access through XenDesktop/XenApp

Ask XenServer's client. To learn more about the XenServer version and how to upgrade, click here to visit

4.Citrix Web site. For more information about licensing, see XenServer 7.1 Licensing FAQ.

The 5.PVS Accelerator requires license server 11.14.

The 6.PVS Accelerator takes advantage of the capabilities of OVS, so it is not available on hosts that use Linux bridging as the back end of the network.

The 7.PVS Accelerator runs on the first virtual network interface (VIF) of the cached VM. Therefore, the first VIF should be connected to the

PVS stores the network to make the caching function work.

How it works:

The PVS accelerator takes advantage of the proxy mechanism that resides in the control domain (dom0) of the XenServer. When this feature is enabled, the PVS target device

(VM) read requests (that is, booting from virtual disks, launching applications, etc.) will be cached directly on the XenServer host (that is, within the physical

In the repository and / or repository. Subsequent VM (on the same XenServer host) boots from the same virtual disk or starts the same application

When programming, the virtual disk (content) will be pushed directly from the cache through streaming technology, rather than from the PVS server. No longer need to go through streaming technology

Pushing from the PVS server greatly reduces network utilization and the amount of processing on the server, thus greatly improving the performance of VM.

PVS Accelerator enabling method:

There are two ways to enable the PVS Accelerator. The first one, as described in the official POC, is through the command. Refer to the command as follows:

Citrix & Vmware 13:40:41

Root@Xen001 ~] # xe sr-list

[root@Xen001 ~] # PVS_SITE_UUID=$ (xe pvs-site-untroduce name-label=PVSedu)

[root@Xen001 ~] # xe pvs-cache-storage-create host=XenServer001 pvs-site-uuid=aef66894-a37a-dc94-0059-0f316090bb2a (UUID of PVS_SITE) sr-uuid=76a4b8ad-fd55-c9fe-523d-28f073ecc427 (UUID of local SSD storage) size=1024

The xe pvs-server-list pvs-site-uuid= Tab key lists all PVS_SITE that have been created

Xe pvs-site-forget uuid= enter the initials of one of the UUID to Tab, and then enter. Delete the PVS_SITE corresponding to this UUID

The second is what I recommend, which is very simple and intuitive. Install this patch on Xenserver, patch name: XenServer-7.1.0-pvsaccelerator.iso (attachment can be downloaded)

After installation, there will be a graphical interface. I believe everyone can handle it.
